Body whine

I didn't fall asleep until 1:00 this morning. Then at 5, I woke up wide awake. With the song "Hey Mama" by the Black Eyed Peas running through my head. Worse, just one certain part of the song... where the guy sings about not wanting to 'squeeze triggers, wanna squeeze tits.' I probably don't want to know what that means to my psyche... but it just kept looping back to that part making it impossible to fall back asleep. So now I'm exhausted and my head hurts and my one shoulder hurts because I have extremely bad posture when I'm sitting at my desk.
